Australian Capital Territory grid · community impact

Based on last week's Australian Capital Territory grid mix (avg 790 gCO₂/kWh), Postcode 2905's 4,873 solar systems typically avoid around 29.45 tonnes of CO₂ every hour during peak generation.

Grid intensity data: Open Electricity (openelectricity.org.au) · 7-day average · updates monthly

Postcode 2905 sits in the top third of Australian Capital Territory for solar uptake, ranking 5th in the state out of 28 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (218 systems, 16% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Postcode 2905's solar community avoids an estimated 47,044 tonnes of CO₂ every year — equivalent to taking 22,402 cars off the road or powering around 9,409 average Australian homes with clean electricity. This is estimated using Australian Capital Territory's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
